[0047] In the following description, a large number of details are discussed to provide a more thorough explanation of the embodiments of the present invention. However, it is obvious to those skilled in the art that the embodiments of the present invention can be implemented without these specific details. In other embodiments, well-known structures and devices are shown in the form of block diagrams rather than in detail to avoid making the embodiments of the present invention difficult to understand.

[0048] Please refer to Figures 1 to 4, the present invention proposes a warning method, system, device and medium for the discharge power of a vehicle battery, which can be applied to the field of electric vehicles. It fully considers the differences between the power source of electric vehicles and traditional fuel vehicles. In a non-fault state, by combining the relationship between the battery discharge power and the battery temperature, it reminds the customer before using the vehicle to avoid entering high-power demand and high-speed driving conditions when the battery is at low temperature and low power.

[0049] Please refer to Figure 1 , in an embodiment of the present invention, a warning method for the discharge power of a vehicle battery may include the following steps.

[0050] Step S10: Obtain the real-time battery temperature, real-time battery power, real-time driving speed and pedal information of the vehicle.

[0051] Step S20: Based on the real-time battery temperature and real-time battery power, obtain the real-time discharge power of the battery.

[0052] Step S30: When the real-time battery temperature is less than the preset threshold temperature and the real-time battery power is less than the preset threshold power, compare the real-time discharge power with the preset threshold power to obtain a power comparison result.

[0053] Step S40: Compare the real-time driving speed with the preset threshold speed to obtain a speed comparison result.

[0054] Step S50: Generate a warning message according to the power comparison result, speed comparison result and pedal information.

[0055] Step S60: Warn the user according to the warning message.

[0056] The following is a detailed analysis through specific embodiments.

[0057] Step S10: Obtain the real-time battery temperature, real-time battery power, real-time driving speed and pedal information of the vehicle.

[0058] Specifically, obtain the battery temperature of the vehicle and compare the battery temperature with the preset normal temperature range and low-temperature range to determine whether the battery temperature is in the normal temperature or in the low temperature. For example, the normal temperature range of the battery of most electric vehicles can be designed to be between 0-40°C, which can enable the battery to maintain the best performance and avoid damage caused by overheating or overcooling. Generally, the ideal operating temperature of the battery is considered to be between 20-35°C. Within this range, the battery can provide the best energy output and charging efficiency, and has the least impact on the long-term health of the battery.

[0059] For example, the battery is extremely sensitive to temperature. At low temperatures, due to the weakening of the battery's chemical properties and the inactivity of electron mobility, the battery's discharge capacity decreases, especially in the condition where the available battery power is low.

[0060] Among them, the pedal information is used to display the acceleration state of the vehicle. The pedal information may include the user stepping on the accelerator pedal and the user releasing the accelerator pedal.

[0061] Step S20: Based on the real-time battery temperature and the real-time battery power, obtain the real-time discharge power of the battery.

[0062] In an embodiment of the present invention, the real-time battery discharge power is a two-dimensional look-up table based on the battery power and the current battery temperature, which is a dynamic value stored in the vehicle control system software, and customers cannot intuitively obtain the current battery discharge capacity through the instrument.

[0063] Step S30: When the real-time battery temperature is less than the preset threshold temperature and the real-time battery power is less than the preset threshold power, compare the real-time discharge power with the preset threshold power to obtain a power comparison result.

[0064] In an embodiment of the present invention, when the battery temperature is within the normal temperature range, the normal temperature range will not affect the battery's discharge power. For example, when the preset threshold temperature is designed to be 0°C, when the real-time battery temperature is less than the preset threshold temperature of 0°C, the battery's performance will decline significantly.

[0065] When the battery temperature is below the threshold temperature, it will affect the battery's discharge power, and the vehicle's overall acceleration performance, maximum speed, etc. will be restricted. For whether an electric vehicle can run normally, it is necessary to compare the real-time discharge power of the vehicle battery with the preset threshold power. The threshold power corresponding to the threshold temperature can be 25kw.

[0066] Specifically, when the battery temperature is below the threshold temperature and a normal real-time discharge power can be provided, the real-time discharge power of the vehicle battery is greater than or equal to the threshold power, so as to meet the normal driving needs of customers. When the battery temperature is below the threshold temperature and a normal real-time discharge power cannot be provided, the real-time discharge power of the vehicle battery is less than the preset threshold power, and the normal driving needs of customers cannot be met under low-temperature conditions.

[0067] Step S40: Compare the real-time driving speed with the preset threshold speed to obtain a speed comparison result.

[0068] Table 1. Simulation Table of Battery Discharge Power and Vehicle Speed

[0069] Discharge power (kW) Vehicle speed (km / h) 80 177 70 168 60 159 50 147 40 134 30 117 20 93 10 77

[0070] As shown in Table 1, in addition to comprehensively considering the battery discharge power capability corresponding to the battery temperature and battery power, it is also necessary to evaluate the maximum vehicle speed corresponding to each battery discharge power step. In the embodiment, a simulation is carried out. As shown in Table 1, through the maximum vehicle speed corresponding to the battery discharge power, the threshold vehicle speed of the vehicle can be better and more accurately confirmed, so as to determine whether the normal driving requirements of the vehicle can be provided to the customer.

[0071] Specifically, when the battery temperature is below the threshold temperature and the vehicle is still in the driving condition on the road, in addition to comparing the real-time discharge power of the vehicle battery with the preset threshold power, it is also necessary to compare the driving speed of the vehicle with the threshold speed. The threshold power can be set to 25 kw, and the threshold vehicle speed corresponds to 105 km / h.

[0072] Step SS50: Generate a warning message according to the power comparison result, speed comparison result and pedal information.

[0073] For example, when the real-time discharge power is less than the threshold power and the driving speed is less than the threshold vehicle speed, it indicates that the battery cannot provide normal real-time discharge power and cannot provide the normal driving requirements of the vehicle to the customer under low temperature conditions, and a warning message is generated.

[0074] When the real-time discharge power is greater than or equal to the threshold power, or when the real-time discharge power is less than the threshold power and the driving speed is greater than or equal to the threshold vehicle speed, it indicates that normal discharge power can be provided and the normal driving requirements of the vehicle can be provided to the customer below the threshold temperature. At this time, no warning message is generated.

[0075] Step S60: Warn the user according to the warning message.

[0076] Such as Figure 2As shown, the vehicle control unit (VCU) 20 can receive the real-time discharge power sent by the battery management system (BMS) 30. The vehicle control unit 20 can be used to generate corresponding warning information based on the power comparison result, speed comparison result, and pedal information in the normal temperature range and low-temperature range. The vehicle control unit 20 can send the warning information to the digital head unit (DHU) 40. The digital head unit 40 is responsible for processing audio, video, navigation, and other in-vehicle infotainment functions. The digital head unit 40 controls the driver information module (DIM) 50, and the driver information module 50 can display warning texts and icon signals to the driver based on the warning information. The icon signal can be a yellow turtle lamp icon or an icon of other colors and other types of graphics.

[0077] Please refer to Figure 1 , in an embodiment of the present invention, in step S50, the step of generating warning information according to the power comparison result, the speed comparison result, and the pedal information may include step S510, step S520, and step S530.

[0078] Step S510: When the real-time discharge power is less than the threshold power, the real-time driving speed is less than the threshold speed, and the pedal information indicates that the user steps on the accelerator pedal, generate warning information.

[0079] Step S520: When the real-time discharge power is less than the threshold power, the driving speed is greater than or equal to the threshold speed, and the pedal information indicates that the user steps on the accelerator pedal, do not generate warning information.

[0080] Step S530: When the real-time discharge power is greater than or equal to the threshold power, and the pedal information indicates that the user steps on the accelerator pedal, do not generate warning information.

[0081] Specifically, when the real-time discharge power is less than the threshold power and the actual driving speed is less than the threshold speed, it indicates that the battery cannot provide normal real-time discharge power and cannot meet the normal driving requirements of the vehicle for the customer under low-temperature conditions, and warning information is generated.

[0082] When the real-time discharge power is less than the threshold power and the real-time driving speed is greater than or equal to the threshold speed, or when the real-time discharge power is greater than or equal to the threshold power, it indicates that the battery can provide normal real-time discharge power and can meet the normal driving requirements of the vehicle for the customer under low-temperature conditions, and there is no need to generate warning information.

[0083] Please refer toFigure 1 , in an embodiment of the present invention, the early warning method for the discharge power of a vehicle battery further includes step S540 and step S550.

[0084] Step S540: Determine the discharge request power of the user according to the pedal information.

[0085] Step S550: Determine whether the discharge request power is greater than the preset safety protection power, and when it is greater, limit the real-time discharge power to the safety protection power or below the safety protection power.

[0086] Specifically, when the driver continuously requests high torque and power through the accelerator pedal within a short time of 10, the battery may experience a rapid discharge process, which will cause its internal temperature to rise, and then cause an increase in the internal resistance of the battery, resulting in a decrease in the real-time discharge power capacity. In extreme cases, if the discharge request power corresponding to the pedal information reaches the safety protection threshold power set by the battery manager (BMS, Battery Management System) 30, the battery manager 30 will take measures to limit the output of the real-time discharge power of the battery to protect the battery from damage.

[0087] Please refer to Figure 1 , in an embodiment of the present invention, the early warning method for the discharge power of the vehicle battery further includes step 701 and step S702.

[0088] Step S701: When the pedal information is that the user releases the accelerator pedal, reset the warning signal.

[0089] Step S702: Clear the warning for the user according to the reset warning signal.

[0090] Specifically, if the driver continuously requests high torque and power through the accelerator pedal within a short time of 10, although the battery itself is in a normal power state, if the real-time discharge power reaches the safety protection threshold power of the battery manager, the battery manager will limit the real-time discharge power of the battery, resulting in the real-time discharge power of the battery being less than the threshold power and a warning message appearing.

[0091] Therefore, after the driver releases the accelerator pedal, if the real-time discharge power is greater than or equal to the available discharge power of the battery, it indicates that the battery itself has sufficient power and can meet the normal driving requirements of the vehicle for the customer. Among them, the available discharge power of the battery means the maximum power that the battery can safely and continuously provide after the user releases the accelerator pedal for 10. The value of the available discharge power of the battery is greater than the value of the threshold power, and the available discharge power of the battery can be 50 kw or 100 kw.

[0092] Please refer to Figure 1, in an embodiment of the present invention, after the step of warning the user according to the warning information in step S60, steps S710 and S720 are further included.

[0093] Step S710: When the vehicle is powered on and started, and the real-time discharge power is less than the threshold power, generate a warning information.

[0094] Step S720: Warn the user according to the warning information.

[0095] Specifically, below the threshold temperature, the discharge power of the battery will be affected, resulting in limitations on the vehicle acceleration performance, maximum speed, etc. of the electric vehicle. To determine whether the real-time discharge power of the vehicle battery can meet the normal driving requirements of the customer, it is necessary to judge the real-time discharge power of the vehicle battery and the vehicle driving speed. Since the vehicle has just been powered on and started and the driving speed is zero, it is not in the driving condition on the road. Therefore, only the real-time discharge power of the vehicle battery can be considered and compared with the preset threshold power.

[0096] Specifically, when the real-time discharge power of the vehicle battery is greater than or equal to the threshold power of 25 kw, it means that the battery can provide normal real-time discharge power, so as to meet the normal driving requirements of the customer. When the real-time discharge power of the vehicle battery is less than the preset threshold power of 25 kw, it means that the battery cannot provide normal real-time discharge power below the threshold temperature and cannot meet the normal driving requirements of the customer.

[0097] Please refer to Figure 1 , in an embodiment of the present invention, after the step of warning the user according to the warning information in step S720, steps S730 and S740 are further included.

[0098] Step S730: When the vehicle is powered on and started again, and the real-time discharge power is greater than or equal to the threshold power, generate a reset warning signal.

[0099] Step S740: Clear the warning for the user according to the reset warning signal.

[0100] Specifically, below the threshold temperature, if the real-time discharge power of the vehicle battery is less than the threshold power, generate and display a warning information. There is a situation where the real-time discharge power of the vehicle battery decreases due to the low temperature range, and the discharge power of the vehicle battery returns to normal in the normal temperature range. When the vehicle is powered on and started again, if the battery temperature is in the normal temperature range and the real-time discharge power is greater than or equal to the threshold power, a cancellation message can be generated to cancel the display of the warning icon on the instrument panel.

[0101] Please refer to Figure 3 In an embodiment of the present invention, a warning system 100 for the discharge power of a vehicle battery may include a first acquisition unit 110, a second acquisition unit 120, a first comparison unit 130, a second comparison unit 140, a generation unit 150, and a warning unit 160.
